Quick question about the optional driver box for the V44 , does it have peak and hold drivers for four injectors in it or is it just a resistor box to limit current if you use low impedance injectors ?

It would be nice if the V44 was available with the 10a peak and hold drivers , can they be a special order that way ?

I can't get into their forum or I'd ask there .

Cheers Adrian .

one little quibble I have with this ecu is the fact you cant select between low/high impedance injectors as you can with many of the other higher end ecu's

are there any explanations for this?

you can with the v88...its only the plug-in boards that have this feature missing.

a solution may be on the cards for this issue

Cool I will look forward to hearing more but for now I'm just going to use a resistor pack.

oh ok good to know!

With the vipec plug in, does it use the V44 boardin your standard casing? also will it support standard GTR injectors, because from what i read, it has some problems with low and high impedance using resistors. because if my afm are buggered im seriously considerign getting on of these, but only if itll run with a stock car once tuned.

Yes, yes, no and yes.

This ecu has been given the honour of being named the "Best ECU" in the latest "Best of the best" High Performance Imports magazine.

The real engine management "leckies" would know for sure but my research leads me to believe that the peak and hold circuitry is different to the saturated system .

PH injectors I believe tend to be low resistance high current ones where saturated ones tend to be high resistance low current .

I've been told the quick dirty method of running high current injectors in a saturated system is to splice in the resistors but you don't have the peak and drop current to snap open and hold the pintle pin like a PH system does .

I did actually speak to Ray Hall and his response is that the V44 is aimed at a price sensitive market segment and I gather to be price competitive had to sacrifice the peak and hold injector drivers and go with the more common trend towards saturated injectors .

Please do NOT make the blind assumption that I'm saying the product is cheap and nasty , the trouble is that so many buy everything on price and if it was made in Xxxxx and sold for $4.99 lots'd buy it .

Something I did read in Honda circles is that someone out there is making good reliable 1000cc saturated injectors and apparently they at times work allegedly better than existing PH ones .

My problem was that getting "affordable" hose barb/tail saturated injectors is not too easy where PH or high current ones are easy and cheap . No good for a wire in V44 though .

My answer could be to use Mazda Rotary turbo O ring injectors and machine shallow rings into them for the short length of rubber fuel hose to bite into under the clamp .

If I could buy a V44 with PH drivers/circuitry I'd do that so Guilt - spill the beans .

He can't "spill the beans" but lets just say the Vi-PEC is evolving. This has been deemed necessary to completely separate the product from another one similar. A lot of the Vi-PEC intellectual property will cease to exist on the similar item. The Vi-PEC brand will be regarded as a world leader in ecu technology and needs its own identity to achieve this. I am of the belief that a lot of features are being held back until the evolution is complete.

I already think i may have said too much...enough for now.

Maybe i should wait for it to evolve and then pick it up with all the gucci stuff.

the chipset will be no different...its just a firmware upgrade and new tuning software if you have already have a Vi-PEC.

The whisper is the new tuning software is the ducks nuts.

I really should STFU...lol

You can call it want you want but the vipec engineers are still the same bunch of engineers that work at Link electro systems NZ. Its funny you call it "Vi-PEC intellectual property" but then there was nothing wrong with giving Link an sm4 plus someone elses "intellectual property" data and telling them to pull it apart and do better.

This does mean the worlds leading ecu will still be made and designed by link in NZ with a few wants put into it by vipec. Do you think Link would want their ecu disadvantaged over the vipec "version" This would take a good sum of money to pass into links hand as remember its them doing the building and designing with wants from vipec. Vipec cant and doesn't make ecus !

Also remember there are ecu's out there that make Link g4/vipec ecu's look very very simple and always will, a vipec will never be the "best" or have the best best technology compared to the likes of pectel or life racing ect...

    • So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
    • Oh and some up-and-comings; New rear drivers wheel bearing. I'll do that this weekend while the diff is out. The car is already up and the d/c axles and missing exhaust will help with space. This is the last bearing for me to do and I've been dragging my feet on it. I also have some new EBC blue stuff pads for the car and some new brake fluid. I haven't ever flushed the fluid in this car and looking forward to it. I have 600 degree fluid to put in. Not exactly "race fluid" but better than the typical stuff I have been using.
    • A proper clutch/plate type mechanical diff with quite a lot of pre-load and high locking % is better for drifting. Much more consistent in its behaviour. A helical can be annoyingly vague and inconsistent in how it responds under the sorts of abuse found in drifting.
    • Some updates here. I pulled the entire interior out, minus some trim to respray the seats with Colourlock dye. It turned out really nice though I accidentally let the dog in the car after and she scratched up the front seat.  This is what it looked like before, the colour was just washing out everywhere but thankfully the leather was in good nic. Then after the respray   And after the bloody dog jumped in The headliner is out waiting to be retrimmed, but it will stay out now until Nov - see why below. I replaced the stereo/headunit with a period-styled Android headunit. I have no after pics, but I'll get some. This is because of the missing pixels. I tried to fix this twice with replacement ribbon cables but couldn't. Also the bluetooth interface I'd bought for this was crap. Then there's the rusty roof. Pics and info in this other thread. I have decided to get this repaired professionally, but I'll update that thread. This is why the headliner will stay out for now. I'll be getting the roof and bonnet resprayed at the same time the rust is fixed. I also had an interesting issue with my drivers door lock.  For a small period I was having issues getting any 12v power to the car - I mean *any*. It would have no dash lights, nothing. It happened while I was at the shops and I couldn't get in the car. So, we had 2 problems. The most pressing here is that I was locked out. I have only a single physical key hole on the car, the drivers door and no amount of turning would unlock the car. Surely it doesn't need power for this? The second issue is why am I losing all power periodically, The battery isn't dead, its almost like the battery isn't even there. Two issues that were surprisingly easy to fix. You fellow BMW over-engineering lovers will appreciate this. The lock in the door has 5 states; mechanical lock, electric lock, neutral, electric unlock, mechanical unlock achieved at -90 degrees, -45 degrees, 0 degrees, 45 degrees and 90 degrees. Although, the unlock is towards the front of the car, so opposite for LHD countries. Sticking the key in and turning 45 left or right is what is used 99% of the time. It activates the central locking etc. 90 degrees is for dead battery access and, obvs, only un/locks the one door. But because the mechanical lock is never used and is 27 years old, it seizes up. I was totally unable to turn the key far enough to get to the mechanical unlock (At the time of locking myself out, I didn't even know this was a thing). I eventually did it with some vicegrips and teflon spray.  I made a quick vid for other E39 peeps.   The battery issue is totally new to me also - It wasn't making sufficient contact between the post and the terminal. The terminal was bolted on tight, but the car wouldn't have power. After checking the battery with my multimeter I accidentally contacted the terminal and the battery post and the car got power. The battery was only a few years old and in good condition. I cleaned the post and the terminal with a wire brush, bolted it back on tight and never had the issue again. I'm still surprised that despite having solid contact it didn't work. Also, the car was getting Warragamba sized pools of water in the back when it rained. My initial concern was another rust problem. But when I went out on Weds while it was raining and while I had no headliner in I could see a steady stream of water coming through the roof mounted aerial. As this aerial is for the (now removed) car phone I pulled it out and whacked a blanking grommet in the hole. It seems fine now. I'm thinking I might get the hole permanently filled when the rust is fixed. Moving forward and things in progress; The tailgate needs some attention. I have taken all the trim off to clean it all and address some small rust spots. I have partially done all of this but I'll finish it up hopefully this weekend. As all the trim are now entirely devoid of trim clips I have bought a heap of strong velcro and I'm hoping it does a good enough job as any of this trim in good condition is super expensive and usually in Europe as we dont have many of the wagons here. Suspension and brakes!!! This is exciting. In the front; New control arms New sway bar links New lower Eibach springs (the only modification I'm planning on this car) M Sport shocks (these came with the car and will replace the longer shocks in the car) New top mounts Used 540i calipers (stock brakes suck!) New 540i disks and pads (22x296 mm for 528 and 30x334 mm for 540i) New front wheel bearings (thank all that is holy for bolt on bearings!) Annnnd in the back; New control arms New sway bar links Adjustable air suspension arms (fool the car into what the current height is so the self levelling suspension can match the new front ride height) New ball joints I'll also be doing a brake fluid flush while I'm in there. I'm planning on switching the car over to the 16's that came with it so I can clean up and respray the M Sport 17's. They've lost a lot of colour over the years and have some gutter rash. None of this will start until the E90 is back.
